[Sbs_gems] [EXTERNAL] Re: Cosmic run tonight

[Ezekiel Wertz]

Hi Kondo,

I personally do not know how to really manipulate the DAQ to do these
tasks. If a DAQ person is available or another GEM person knows how to
properly manipulate the DAQ to accomplish this, I have no problem taking
data like this. Also how long (i.e. how many events of cosmic data) would
one want at each one of these DAQ configurations.
